The New York State Department of Transportation recently completed the $21.1 million Adirondack Northway project in Warren County.
The project replaced two bridges constructed in the mid-1960s that carry Interstate 87 over U.S. Route 9 with a single structure between Exits 22 and 23 in the town of Lake George.
The new 323-foot-long, two-span, steel multigirder bridge has a minimum vertical clearance of 49 feet 6 inches above U.S. Route 9 and a projected lifespan of 75 years. It was built between the original two spans and used a cement-concrete mixture that, compared to concrete alone, is stronger and more durable and contributes fewer greenhouse emissions during the production process.
Construction began in 2022, and the location of the bridge allowed two of the three travel lanes in each direction to remain open throughout most of the project.
“This new bridge along the Adirondack Northway will ease travel and help ensure the long-term durability of a vital connector that helps power the economic engines of the Capital Region, the North Country and all points in between,” Department of Transportation Commissioner Marie Therese Dominguez said.
The section serves interstate and regional traffic and connection to Canada.
The federal Infrastructure Investment and Jobs Act funded 90 percent of the project.
